Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621794, here are decompositions:

47 + 8621747 = 8621794
101 + 8621693 = 8621794
113 + 8621681 = 8621794
317 + 8621477 = 8621794
383 + 8621411 = 8621794
557 + 8621237 = 8621794
593 + 8621201 = 8621794
641 + 8621153 = 8621794

Showing the first eight; more decompositions exist.
